When two objects are so close together that the distance between them is about the same size as quantum fluctuations called virtual particles, they’re pulled together. This effect, caused by the ...

A repulsive quantum force, opposite of casimir force, has been verified and measured. This is the cover story, [Measured long-range repulsive Casimir-Lifshitz forces], of the Jan 8, 2009 Nature ...

We use the extended Lifshitz theory to study the behaviors of the Casimir forces between finite-thickness effective medium slabs. We first study the interaction between a semi-infinite Drude metal and ...

Researchers have discovered a "repulsive" light force that can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity. A ...

A newly created material withstands vertical loads applied in the direction perpendicular to its layers while distorting in the horizontal direction. It is promising as a vibration-damping material. A ...

A team of Yale University researchers has discovered a “repulsive” light force that can be used to manipulate components on silicon microchips, meaning future nanodevices could be controlled by light ...

The experimental verification that a bizarre quantum effect — the Casimir force — can manifest itself in its repulsive form is pivotal not only for fundamental physics but also for nanotechnology. The ...

A complex interplay of energetics and dynamics governs the behavior of nanocrystals in solution. These dynamics are usually interpreted in terms of the theory developed by Derjaguin, Landau, Verwey, ...

New Haven, Conn.—A team of Yale University researchers has discovered a "repulsive" light force that can be used to control components on silicon microchips, meaning future nanodevices could be ...

A quantum effect that causes objects to repel one another – first predicted almost 50 years ago – has at last been seen in the lab. According to Harvard physicist Federico Capasso, a member of the ...

A strange quantum force could be used to make tiny machine parts levitate in frictionless nanomachines of the future. The Casimir effect describes the attraction that occurs between two parallel, ...
